To all whom. it may clone-ern:`

Be it known that I, OTToE. WEIDLICH, a vcitizen of the United vStates ofAmerica, and a resident of Cincinnati, in the county of' Hamilton andState of Ohio, have invented certain new andauseful ImprovementsinFountain- Pens, of which the following isa specification.

This invention relates to certain improvements in fountain-pens, andmore particularly in the feeding devices commonly employed .therein forfeeding the ink from the reservoir to the pen-point; and the object ofthe invention .is to improve and simplify theconstruction of suchfeeding devices in such a way as to afford means for preventing thedropping of ink from the` pen-point in case the inli'is fed too freelyat times, whereby the operation of such feeding devices isimproved andthe writing is rendered uniform and regular and blotting caused by suchydropping ink from the pen-point is avoided. 1,

The invention consists in certain novel features of the construction,combination, and arrangement of theseveral parts of the improved feedingdevices whereby certain .important advantages .are attained andthe-devices are rendered simpler, cheaper, and otherwise better adaptedand more convenient for use than variousother similar devices heretoforeemployed, all as Will'be hereinafter fully set forth.

The novel features of the inventionwillbe i carefullydefined in theclaims.'

In the accompanying drawings, which serve to illustrate my invention,Figure 1 is ay sectionalview taken axially through the end porl tion ofa fountain-pen provided vwithffeeding devices embodying my invention andshowing in elevation theupper face -of said feeding'devices.

Fig. 5 is-a View showing infplan and detachedfrom the pen a feedof surplus n ingdevice-constructed' in amodiiied form andv embodying my invention, thisform of the device being especially .designed for use in connectionwithpen-points of small size. Fig. 6

hthe feeding deviceras shown. in Figs. 9 and 10. Fig.k 12 1s atransverse section taken Figs. 9,10, and 11, the plane of the sectionlbeing 'along line CZ @Z in Fig. 10.k Fig. 13 is a transversesectionshowing still another modifiedform o f the. improved feedingdevice.

As shown in the views, and referring particularlyto Figs. 1,`-2,i 3, andl of the drawlpen, and 2 indicates the screw-plug commonly l employedfonclosi-ng the open end of the same and for 4holding thepen and feedingdevices, andl 3l indicates .the `removable cap adapted vto 4.fit uponv'said plugto yguard or shield the penpoint 4L. when -thefdevic'e is notrequired for usen.l -.indicates the feeding device as a whole, L

-saiddevice being in the form of a cylindrical rod `or ,piece .passedthrough the plugs-S and having a shoulder 6 at the forward vendof saidplug, being provided abovesaid shoulder 6 at its said forward ,end witha projecting tonguel or feeder 7, the upper surface of which is made rconvex to conform lto the .perimetral surface through .thefeeding-device asv-.illustrated in Y ings, lindicates .the reservoir ofa fountainof the body portion 5 and to the underside of '4; thepen-point4,which is fitted in the'screw-plugl .s 2 above said convexsurface, with its nibs projecting, as shown in Fig-2, inposition for useIVOO Fig. 1, to a point near but separated from the forward end of thefeeder, as indicated at 9, at which point said forward end of the feederis slightly flattened to permit the inl( to be fed readily to the pen 4.The tongue or feeder 7 at the forward end of the body portion isprovided at opposite sides of its central feedgroove 8 with longitudinalslots or channels 10 10, parallel with the feed-groove and extendedthrough said tongue or feeder from its upper to its lower surface, asillustrated in Figs. 3 and 4, and these slots or channels 10 10 formoveriiow chambers or receptacles in which is adapted to be received andheld any surplusage of ink which may be fed to the pen-point from thegroove 8 over and above what is required or desirable for writing, suchsurplus ink flowing readily th rough the interstices between thepen-point and the convex upper face of the feeder or tongue 7 into theoverfiow-chambers, as will be readily understood. In this way it will beseen that the surplus ink over and above what isv required in the use ofthe pen is carried to the overflow chambers or receptacles at oppositesides of the feed-groove and is prevented from running down and droppingfrom the nibs of the pen-point, so that the liability of drops of inkfalling from the pen and forming blots in the use of the same isaltogether avoided and the action of the pen during writing is madeuniform and regular.

In the construction shown in Figs. 1 to 4 the grooves or channels 10 10are closed at their forward ends, as seen at 11 11, by the forwardextremity of the tongue or feeder 7, through which said slots orchannels are not extended, and are also closed along their outer sidesby the lateral portions 12 12 of said tongue or feeder, and said groovesor slots 10 10 are made quite narrow, so as to avoid liability of theink contained therein dropping from the feeder during the use of thepen; but when the device is used in connection with small pens theclosure of the outer sides of the grooves or slots by the lateralportions of the feeder is not essential, since the overhanging sides ofthe pen-point will rest closely adjacent to the sides of the feeder andwill accomplish the same result. Y

. In Figs. and 6 I have shown a form of feeder of this nature, whereinthe slots or channels 10a 10a are open along their outer sides, saidopen outer sides being adapted to be closed, as indicated in Fig. 6, bythe over- `hanging sides of the pen-point, whereby the ink contained inthe overflow-chambers thus produced will be held and prevented fromdropping from the pen during writing.

In Figs. 7 and 8 I have shown another form of the improved feedingdevice, wherein the grooves or slots 10 10 at opposite sides of thefeed-groove are formed between the tongue or feeder 7 and an auxiliarytongue or projection 13 extended from the body portion 5 of the feedingdevice beneath the tongue or feeder 7, the under side of the feederbeing in this case made convex and the upper surface of the auxiliarytongue being concaved to correspond with but spaced from said lowersurface of the feeder to produce the overiow-chanibers 10 10 between theopposite sides of the tongue or feeder 7 and the outer edge portions 1212 of the auxiliary tongue 13. The central portion 14 of the spacebetween the tongue or feeder 7 and auxiliary tongue 13 in this form ofthe device affords acommunication between the two overiiow chambers orgrooves 10 10. In Figs. 9, 10, 11, and 12 I have shown another form ofthe device, wherein thel auxiliary tongue or projection 13 is made witha convex upper surface, while the under side of the tongue or feeder 7is concaved to produce the overiiow chambers or grooves 10" 10b, whichare thus disposed lengthwise upon the under side of the device, beingconnected centrally with each other, and the forward end of theauxiliary tongue or projection 13" is curved upward, as seen at 15, andis arranged to engage under the pen-point at a location in advance ofthe forward end of the feeder 7, being spaced apart therefrom to permitthe surplus ink to iow down within the grooves or chambers 10b 10". Thebent portion 16, at the forward part of the auxiliary tongue 13, isreduced in thickness to facilitate the downward flow of. the surplusink. The upwardly-curved portion l5 beneath the pen-point is in positionto guide the surplus ink therefrom into the overflow-chambers when toomuch ink is supplied and at other times guides ink from theoverflow-chambers to said pen-point to render the operation of thedevice in writing regular and uniform.

In Fig. 13 I have shown still another modified form of the device,wherein the under side of the feeder 7is rounded or convex and theauxiliary tongue or projection 13". is made with a flattened upper face,between which Vand said rounded underside of the feeder the slots orchannels 10c 10c are present at opposite sides of the feed-groove 8,said grooves or channels 10c being centrally connected by a space 14L ina way similar to that shown in Figs. 7 to 12; but this central space isreduced in thickness, so as to more eifectually hold the ink and preventblotting.

In each of the several forms of the improved pen herein shown it will beobserved that the overiiow grooves or cuts are entirely independent ofthe feed-gioove, being separated therefrom by surfaces on thefeedingtongue along opposite sides of the feed-groove and adapted forcontact upon the under surface of a pen-point when the latter is inposition in such a way as to etfectually prevent the iiow of inktransversely of the tongue from the feed-groove into theoverflow-chainbers until the ink shall' have reached the extremity ofthe pen-point, at which position IOO IIO

the*` surplus supply of ink is free to 'flow into the overflow-chambersand will be held therein and prevented from dropping in blots from thepen. From the above description it will be seen that the improved penconstructed according to my invention is of lan extremely simple `andinexpensive nature and is especially well adapted for use, since thefeeding devices herein shown and described effectually-prevent thedropping of ink from the pen-point, so that blotting is prevented, andthe action of the pen is made uniform and regular, any surplus inksupplied through the feed-groove being held within the overiiow-chambersuntil it is required for use, when it is permitted to Having thusdescribed my invention, what I claim, and desire to secure by LettersPatent, is-
